SPECIFICATION forming part of Letters Patent No..288,268, dated November 13, 1883. i Application filed December 2], 1881. (No model.) i

.yarns are inserted in and secured to the body of the fabric and the object of the invention A is to enable the ends of the rows of tufting material inserted from one side of the position of the warp-threads in the loom to be turned toward the side fromwhich theyhave been inserted, so that both ends of the tufting matei rial may be at the same side of the fabric.

The `invention consists of certain combinations of mechanical devices which are recited in the claims at the close of this specification. In order'that these combinations may befully understood, We have represented inthe accompanying drawings, and will proceed to describe, certain parts of a loom embodying the invention in the best form at present known to us. 1

Figure l represents a longitudinal' section of parts ofthe loom.y Figs. 2, 3," and 4t represent detachedportions oi' the loom.

' As the invention has reference to particular portions of the loom, the other parts thereof may be constructed substantially as described and represented in the Letters Patent of the United lStates No. 186,374, with such variations only as may be necessary by reason of the present invention, as hereinafter set forth; The Warp and the vweft threads or filling of the fabric may be held and operated substan- 4tially as they are in other Moquettecarpet looms. y

' The tuftingisby preference applied to a series of spools, which are carried by means of chains or othermechanism, and are presented in succession to the devices by which they are brought to and removed from the vicinity of yframe or carriage,

l the fabric for the 'purpose of having the tufts Each spool is fitted in a'spool which is provided with a roiv of tubes or needles, h', to hold the ends of the tufting material, and the frame shoiild also be .provided with a spring-brake to prevent the turning of the spool, except when the placed therein. f

tufting material is pulled off it by the operay tion of f the mechanism. In order that the spool-frame may be moved toward and from the place in the loom at which the tufting is to be applied to the warp-threads, the looni is preferably provided with a pair of movable arms, K, (one at each side of the loom,) which arey connectedwith a rock-shaft, K2, which is Vcaused to rock, so as to move the ends of the movable arms toward andfrom the 'position of the Warp in the loom. The movable arms K are preferably provided With clutches to grasp the ends of the spool-frames, and the said arms are preferably connected by pivots with the rocloshaft arms K, (one foreach movable arm so that the fiist may be moved laterally in opposite directions to grasp and release 'each spoolframe in succession. The said movable arms are caused to move toward yand from the position of the fabric by means of a cam, K3, operating upon said arms through the intervention ofl a friction-wheel, Kt, cam-lever K5, lrod K6, rock-shaft arm K, and the rock-shaft K2, and the lat-eral` movements of the movable arms to enable them to grasp and release the spool-frames may be effected by the same means as is' described for that purpose in l at ent No. 233,290. g

' In order that the present invention may be embodied in the loom, it is provided with means for producing a blast or jets of air at the side of the Warp opposite that from which the tufting material isintroduced, so that the 2 f y assmis In the exampleof the invention represented in the accompanying drawings a blast of the requisite force is furnished by a cylinder, A, which is tted with a piston, B, containing an inlet-passage and a valve, a, for the entrance of air when the piston is drawn backward in the loom. The piston is connected by means of a connecting-rod, b,with a lever, B2,which is forced forward at the proper time, in the operation-of the loom,bymeans of a cam, B3,

i secured to and caused to revolve with the compressed during the advance of the piston t v in the cylinder is applied tothe tufting matey rock-shaft.

rial by means of an air-pipe, C, which extends crosswise of the loom, beneath the position of -the warp m, and is tted with a series of aj utages from which the air can be ejected in jets. In this instance the air-pipe is supported in the loom by being connected at each end by an arm, c7, with the rock-shaft F2 of the lay F of the loom, so as tovibrate on said Each pipe-arm, when in a forward position, (as represented aty Fig. 1,) is supported by a bracket, o8, connected with the frame of the loom, and when the pipe-arms rest against these brackets the air-pipe C is so far forward in the loom as not to interfere with the operation of the'other parts thereof. When the blast of air is to be applied to the tufting material, the air-pipe is moved backward in the loom to place its ajutages in the proper position to operate upon the ends of the tufting material.' In order that this 1n ovement may be effected by the lay-cam, the lay is fitted at each end with a hook, o9, whose point engages with the corresponding pipearm, c7, and these hooks, when the lay is moved backward after beating up the binding-lling, as hereinafter described, pull the pipe-arms and the air-pipe backward to the proper position for ejecting the air.

The air-pipe O is connected by means of several flexible pipes, e, with the exit-pipe C of the blast-cylinder A, and the passage of air from the blast-cylinder to the exit-pipe is controlled by a valve, C2, constructed to slide in a valve-chest, C3. The valve is tted with a valve-rod, c', to which a spring, c2, is applied, which constantly tends to hold the valve open, and to open it after it is closed. The end c3 of the valve-rod c is extended backward and is bent sidewise, so that it is within the range of motion of an extension, b2, of the blast-lever B2; hence if the valve be open the next succeeding backward movement of the lever B2 draws the valve backward in its chest and closes it. In order that the valve may be kept closed until the blast is to be used, the valve- `rod c is iitted with a projection which engages with a latch, c", whenever the valve-rod-is moved backward.`

The loom, parts of which are represented in the accompanying drawings, is constructed to introduce into the warp of the fabric four shoots of filling or weft thread for each row of tufting material, and consequently the lay-cam F3 is made with four projections, f f f f2, to operate the lay for each revolution of the camshaft G. Three of these projections, f f f, are preferably duplex to impart a double beat to the lay for beating up each shoot of coarse filling. The fourth projection, f2, is preferably single-pointed, and operates the lay for beating up a shoot of finer filling for binding. the tufting material in thev fabric. The blast should be applied to the ends of the tuftingyarns after the shoot of binding-filling is beaten up, and in .order to simplify the loom a provision is made for letting on the blast by the movement of the lay/F. For this purpose the shank of the valve-latch c4 is fitted with a slotted rod, c5, whose slotted end ts upon a pin secured to an arm, c6, which is projected from the rock-shaft F2 of the lay. The slot of the rod is of such length that inthe ordinary backward movement of the lay, as permitted by the form of the lay7cam F3, the pin of the arm c6 vibrates in the slot without moving the latch-rod c5 or the latch ct,- but the portion g of the rim of the lay-cam,`which controls the backward movement of the lay after the binding filling is beaten up, is depressed more (by being nearer the aXis of the cam-shaft) than the residue, so that the lay F may then move backward far enough to cause the pin of the arm cto move the latch-rod c5 and raise the end of the latch c4 from the valve-rod c, thereby releasing the valve-rod and valve, and permitting the valve to be opened by the spring c2, the result of which is that the compressed air in the blast-cylinder and pipes escapes through the aj utages of the air-pipe C. When the air-pipe C is moved backward with the layr `F, as represented in the drawings, they same movement of the lay brings the ajutages of the air-pipe close to the lower ends of the tufting material, so that the blast is directed against said ends by the air-pipe, and they are'blown backward and upward into or Athrough the warp, and if these ends are not blown through the warp the raising of the warp-threads at the sides of the tufting material, to form the next succeeding shed for the passage of the filling, raises the said ends high enough to permit the lling-thread to be driven forward beneath them by the action of the lay F.

-When the loom .is in operation, the tufting material is moved to the warp-threads bythe action of the movablearms K, and is introduced between the warp-threads and placed within the range of the blast from the air-pipe 0 by means of the series of tubes or needles h. The subsequent action of the blast bends the end of thetufting material backward and upward toward the side of the warp-threads from' which the tufting material was inserted, and the lay insures the completion of the operation by.I

IOO

beating up the next shoot of filling against the tuiting-yarns. v

The blast-earn 1B3 is by preference constructed as represented in the drawings, so as to gradually compress the air and produce the greatest compression justprevious to the opening of the blast-valve C. l It is not, however, necessary to the invention that the blast should be generated by a cylinder or other blowing deviee connected with the loom, it being obvious that a blowingengine separate from the loom may be employed to supply the air-pipe C of the loom or the air-pipesof a number of looms in the same establishment. It is also not essential to the invention that the air-pipe should be carried by the lay and be moved by the lay-earn F3, or that the latch c* and valve G2 should be' operated by the lay, because special devices may be used to operate the airpipe and the latch of che valve when the lay has been :moved backward in the loom suffreiently to permit the ends of the tufting niaterial to be blown upward; but the eonneotion of the blast-pipe and the valve with the other members, `so that they may be controlled by set forth, ofthe movable arms at one side of 4o y the position of the warp, the air-pipe arranged at the opposite side thereof, and the valvefor controlling the exit of air through the air-pipe.
